How to File a Workplace Safety or Health Complaint with OSHA

Updated

You can file a workplace safety or health complaint with OSHA by submitting it online, by phone, by fax, by mail, or in person at the nearest OSHA office. The channel you choose mainly affects speed and follow-up: an online or phone report is the fastest way to start, while a signed written complaint is what triggers an on-site inspection. You do not need to be an employee of the company, and you can ask OSHA not to reveal your name.

Choose the Right Channel

Channel Best for What happens next
Online form Fastest submission; you can describe hazards in detail OSHA reviews and routes it to the area office
Phone Urgent or hazardous situations; asking questions first A compliance officer takes the details
Fax or mail Submitting a signed written complaint Signed complaints are more likely to lead to inspection
In person Complex situations or documents to hand over You speak directly with area office staff

If the danger is immediate — a worker could be killed or seriously hurt before OSHA arrives — call your local OSHA area office or the OSHA emergency line rather than relying on a web form.

What to Include in Your Complaint

The more specific the information, the easier it is for OSHA to act. Include:

  • Employer name and address, plus the worksite address if different from the main office
  • The specific hazard — what it is, where it is, and which workers are exposed
  • How long the hazard has existed and whether anyone has been injured or made ill
  • Your contact information, if you are willing to be contacted for follow-up
  • Whether you want your name withheld from the employer

You can file even if you are not sure of the exact OSHA standard that applies. Describe the condition and let OSHA determine which requirements are relevant.

Formal vs. Informal Complaints

This distinction matters because it determines whether OSHA can inspect.

  • Informal complaint: You report a hazard without a signed written statement. OSHA may contact the employer by phone, fax, or letter and ask them to fix the problem and respond in writing. No inspection is guaranteed.
  • Formal complaint: You submit a written, signed complaint (or sign one after an oral report) that alleges a violation and states that a hazard exists. If OSHA determines the hazard is serious, it can conduct an on-site inspection.

A signed complaint from an employee or employee representative carries more weight than an anonymous tip. If you file online or by phone and want the formal route, say so explicitly and confirm that OSHA has your signature on file.

Your Right to Be Protected from Retaliation

OSHA's whistleblower protections apply when you report a safety or health concern. Under the Occupational Safety and Health Act, employers cannot fire, demote, harass, or otherwise retaliate against you for filing a complaint, participating in an inspection, or exercising other rights under the Act.

If you believe you were retaliated against, you generally must file a whistleblower complaint within 30 days of the adverse action for the OSH Act's Section 11(c) protection. Other laws OSHA enforces have different deadlines, sometimes as short as 30 days and sometimes longer. Missing the deadline can bar your claim, so file as soon as possible.

Practical Tips Before You File

  • Document the hazard first. Note dates, times, locations, equipment involved, and any symptoms or injuries. Photos help if you can take them safely.
  • Check whether it is already reported. A prior complaint or open inspection may mean your report gets added to an existing case.
  • Keep a copy of anything you submit and note the date.
  • Use the area office, not the national office, for faster handling — complaints are processed regionally.
  • Ask about confidentiality at the time you file if you are worried about your job.

Common Sticking Points

  • Anonymous complaints rarely lead to inspection. Without a signed statement, OSHA usually pursues an informal resolution instead.
  • Vague descriptions slow things down. "Unsafe conditions" is hard to act on; "no guard on the table saw in Bay 3" is not.
  • Retaliation deadlines are short. Do not wait to see how things play out before filing a whistleblower complaint.
  • State-plan states may differ. Some states run their own OSHA-approved programs with their own complaint procedures — check whether your state has one before filing.

For the current online form, area office contacts, and whistleblower filing details, go directly to osha.gov and use the complaint and whistleblower sections rather than a third-party summary, since procedures and deadlines can change.
